I am trying to use apache-2.3's mod_proxy_fcgi in 2.2.13. It seems to be built and run all right.
But I have noticed that the SCRIPT_FILENAME has been changed to "proxy:balancer://xxxxxx", it cann't be recognized by the remote PHP backend. So the request failed. In my opinion, the remote PHP backend use the SCRIPT_FILENAME to find the script file. But the PHP and the Apache may be in different computer, so the Document Root may be different. is that means the PHP shouldn't rely on the SCRIPT_FILENAME? then how can the PHP know which script file to execute? Or, can the mod_proxy_fcgi make the SCRIPT_FILENAME to be the real file location? then the PHP backend in the same computer will find the file correctly.
